H A Dintel_audio.cdiff 8e056b50d92ae7f4d6895d1c97a69a2a953cf97b Tue Apr 30 11:18:25 CEST 2024 Chaitanya Kumar Borah <chaitanya.kumar.borah@intel.com> drm/i915/audio: Fix audio time stamp programming for DP

Intel hardware is capable of programming the Maud/Naud SDPs on its
own based on real-time clocks. While doing so, it takes care
of any deviations from the theoretical values. Programming the registers
explicitly with static values can interfere with this logic. Therefore,
let the HW decide the Maud and Naud SDPs on it's own.
